Surah Kahf ayat 70 Tafsir Quran 18:70

﴿قَالَ فَإِنِ اتَّبَعْتَنِي فَلَا تَسْأَلْنِي عَن شَيْءٍ حَتَّىٰ أُحْدِثَ لَكَ مِنْهُ ذِكْرًا﴾
[ الكهف: 70]

18:70 He said, "Then if you follow me, do not ask me about anything until I make to you about it mention."

He said ‘If you follow me then do not question me lā tas’alnī a variant reading has lā tas’alannī concerning anything that you might find objectionable in what I do according to your limited knowledge and be patient until I myself make mention of it to you’ in other words until I mention it to you with an explication of the reason for it. Moses accepted his precondition bearing in mind the respect which a student should exercise in the presence of a teacher.

Therefore, said the teacher if you should follow me, then do not look for the how and the why and the wherefore until I have given you an account of it

Musa meeting with Al-Khidr and accompanying Him Allah tells us what Musa said to that learned man, who was Al-Khidr.
He was one to whom Allah had given knowledge that He had not given to Musa, just as He had given Musa knowledge that He had not given to Al-Khidr. قَالَ لَهُ مُوسَى هَلْ أَتَّبِعُكَ ( Musa said to him: "May I follow you..." ) This is a question phrased in gentle terms, with no sense of force or coercion.
This is the manner in which the seeker of knowledge should address the scholar. اتَّبَعَكَ ( I follow you ) means, I accompany you and spend time with you. عَلَى أَن تُعَلِّمَنِ مِمَّا عُلِّمْتَ رُشْداً ( so that you teach me something of that knowledge which you have been taught ) meaning, teach me something from that which Allah has taught you so that I may be guided by it and learn something beneficial and do righteous deeds.
At this point, قَالَ ( He said ) meaning, Al-Khidr said to Musa, إِنَّكَ لَن تَسْتَطِيعَ مَعِىَ صَبْراً ( Verily, you will not be able to have patience with me! ) meaning, `You will not be able to accompany with me when you see me doing things that go against your law, because I have knowledge from Allah that He has not taught you, and you have knowledge from Allah that He has not taught me.
Each of us has responsibilities before Allah that the other does not share, and you will not be able to stay with me,' وَكَيْفَ تَصْبِرُ عَلَى مَا لَمْ تُحِطْ بِهِ خُبْراً ( And how can you have patience about a thing which you know not ) `For I know that you will denounce me justifiably, but I have knowledge of Allah's wisdom and the hidden interests which I can see but you cannot.' قَالَ ( He said ) meaning, Musa said: سَتَجِدُنِى إِن شَآءَ اللَّهُ صَابِرًا ( If Allah wills, you will find me patient, ) with whatever I see of your affairs, وَلاَ أَعْصِى لَكَ أمْراً ( and I will not disobey you in aught. ) means, `I will not go against you in anything.' At that point, Al-Khidr, upon him be peace, set a condition: قَالَ فَإِنِ اتَّبَعْتَنِى فَلاَ تَسْأَلْنى عَن شَىءٍ ( Then, if you follow me, ask me not about anything ) do not initiate any discussion of the matter, حَتَّى أُحْدِثَ لَكَ مِنْهُ ذِكْراً ( till I myself mention of it to you.
) meaning, `until I initiate the discussion, before you ask me about it.'

( He said ) Khidr said: ( Well, if thou go with me ) if you keep my company, O Moses, ( ask me not concerning aught ) about what I do ( till I myself mention of it unto you ) until I proceed to explain it to you.

He (Khidr) said: "Then, if you follow me, ask me not about anything till I myself mention it to you."
